Is it incompatible for a man born in 1969 to marry a woman born in 1970? There is no such thing. You have to decide whether it is good or not. As long as they love each other, there will be no problem.
If you are asking about love and marriage, this is not directly related to the zodiac sign. So the zodiac sign cannot be seen.
If you are not in love yet, it depends on whether you are in unrequited love or whether you are in love with each other! Fate is determined by fate, and you can seize the opportunity yourself. There will be no results in secret love. If you like it, you have to let the other person know.
If you are in love or married, whether you have a future and whether you can be happy depends on whether you can manage this love well. Learn to be tolerant, learn to cherish, respect and love each other, be honest with each other, and be sincere in exchange for true love. The future will definitely be bright!
